Change the size of virtual memory
If you receive warnings that your virtual memory is low, you'll need to increase the minimum size of your paging file. Windows sets the initial minimum size of the paging file equal to the amount of random access memory installed on your PC, and the maximum size equal to three times the amount of RAM installed on your PC. If you see warnings at these recommended levels, then increase the minimum and maximum sizes.
